GLASS-WORKING MACHINE.

Specification of Letters Patent. Patented Mar, 28, 1911.

Application filed June 2, 1910. Serial No. 564,662.

thereof designed for employment especially in the manufacturing of bottles.

The object of my invention is the provision of a machine of the character mentioned by means of which bottles of perfect form may be made with ease and expedition.

A further object is the provision of a.

tion, and in which,

Figure 1 is a central vertical longitudinal section of a glassworlring machine embody o5 ing the preferred form of my invention, is a vertical section at right angles i 1, and Figs. 3 and s are slightly entransverse sections taken on lines and y respectively of Figs. 1 and 2.

Terring now to the drawings 1 indithe supporting frame of the device 1 is suitably mounted upon wheels 2, eby ready transportation thereof may he e5." *ed. The frame 1 comprises an uper oriaontal table 3 and a lower parallelly ing table 3, said tables 3 and 3 be inc; spaced at and rigidly secured together by posts a and braces l. Arranged substantially centrally upon the upper side of the 3 iso. metallic disk 5. Haying its lease rigidly secured to saidv disk is an upi v extending post 6.

drawings forming a part of this specifica t. Ttotatably mounted upon the upper reduced end portier, of post are the slotted lugs T of V iilar parts 8 and El bf the mold 10. llie latter is of cylindrical exterior form,

the sin machines and more specifically to that class the interior thereof comprising the upper enlarged portion 11 which is adapted to form the body of the bottle, and the lower "reduced neck-forming portion 12. Formed upon the outer surface of the mold part 8 adjacent the outer longitudinal edge thereof are vertically alining lugs 13 in which is pivotally secured a locking member 14, 15 indicating the operating handle therefor. The oifset outer end of said lever is adapted to engage a lug 16 formed upon the mold part 9 adjacent the outer longitudinal edge thereto, and whereby said mold parts 8 and 9 maybe securely locked in closed position. Projecting from the mold part 9 is a handle 17, by means of which and'the handle 15 of the member 1% said mold parts may be readily swung apart when the same are unlocked.

The upper end of the mold 10 is open for the reception of the cylindrical blank-forming member 18 which is mounted for co axial movement with said mold. Formed centrally through the member 18 is a bore 19 which is adapted to register with the reduced portion 12 of said mold. The guide 20 of the bore 19 is flared or enlarged, as clearly illustrated to facilitate pouring of molten glass into said bore.

. The upper end of the member 18 is secured in the upper end of a substantially rectangular frame 21, the vertically disposed parallelly extending bars 22 of the latter 'being slidably mounted in tubular guides 23 arranged upon the table 3, said bars as seen, also projecting through the latter. Mounted upon the table 3 (Jo-axially with the mold 10 is a cylinder 24. Operating in said cylinder is a piston 25 and a piston rod 26. The upper end of the piston rod 26 projects exteriorly of the cylinder 24: into close proximity with the lower transverse bar 28 of the frame 21, the upper extremity of said piston rod being bifurcated as at 27 for the reception of said bar. The arrangement is such that, when the piston 25 and hence the piston rod 26 is at its upper terminal of movement the member 18 will be elevated above the mold 10 so that the lower extremity thereof will be positioned slightly above the upper extremity of said mold. Communicating with the upper extremity of the cylinder 24 is a pipe 29 and communicating with the lower extremity of said arrangement, it will be seen that in order to effect the vertical movement of the piston Y 25 and hence the elevation of the= member to operate the handassage from the pipe en it-is desired to 18, it is only required piece .33 to open the 31. to the pipe--; 30.

'IOWGI' said piston said handle 33 needs only to be 0 erated to establish a connection between t d pipe 29 and the pipe 31. When this is-done, the piston 25 and hence the piston rod 26 will evidently be forced to its lower terminal of movement. When said piston rod is lowered the member 18 will drop by gravity to its normal position within the mold 10.- a

Secured to the u per end of the mold part 8 is a channel gui e 34in which is slidably mounted a closure 35 which is adapted by means of a handle 36, when the member 18 is in elevated position, to be slid into position to close the upper extremity of the mold.

Slidably mounted in the table 3 and the member 5 co-axially with the mold 10 is a tube 37. The lower extremity of the tube 37 is secured to a cross piece 38. The extremities of the cross piece 38 are slotted for the reception of guide rods 39, downward movement of said cross pieces and hence the tube 37 being limited by nuts 39 threaded upon the lower extremities of said rods 39. Compression springs 40 interposed between the ends of the cross piece 38 and the table 3 are adapted to normally hold the former and hence the tube 37 at its lower extremity of movement.

41 indicates a lever the rearward extremity 12 of which is fulcrumed to a depending post 13 secured to the under side of the table 3. Said lever is provided with an elongated slot 44 which is engaged by a pin 45 carried in. a bifurcated lug 16 depending from the cross piece 38. Thus an operative connection between the tube 37 and the lever 41 is established, vertical movement of said tube being, with efiected by oscillating said lever. Communicating with the tube 37 adjacent its lower extremity is a flexible pipe or hose 17 which is connected at its outer extremity to the compressed air supply. pipe 31. The passage through the pipe 4:7 is controlled by a valve 18, 49 indicating the operating handle of said valve.

Theoperation of the device is as follows: With the blank-former 18 at its lowermost position, that is within the mold 10, the proper quantity of molten glass is poured into said blan ormer a portion of this neck of the bottle.

effecting the blowing of the glass the construction described,

glass flowing down into the reduced portion 12 of the mold to form the neck of the bottle. The tube 37 is then, by means of the lever 41, forced upwardly into the molten glass blank contained inthe member 18, to the position indicated in dotted lines in Figs. 1 and 2, to form the passage through the The member 18 is now elevated, such elevation being effected, as before stated, by simply operating the valve 33 to open the passage to the pipe 30. The closure 35 is now slid to closing position over the upper end of the mold. Through the medium of the valve 48 air under pressure is then blown through the tube 37 blank into the form of the interior surface of the mold. Owing to the fact that tube 37 is open at the top and extends into the mold and blank only to the depth of the neck of the bottle, the portions of glass to be moved farthest by the air admitted through said tube lie immediately above the opening in said tube, whereby they are directly affected by the incoming air for elevation and detachment from said tube. Thus the bottle is formed. Upon being sufficiently cooled the finished bottle may be readily removed after lowering the tube 37, disengaging the locking member 1a, and swinging the mold parts 8 and 9 apart.

With the construction disclosed it will be i seen that a machine of durable and economical design is provided, and one by means of which bottles may be made with great rapidity, it being evident that, with one familiar with devices of this nature operating the machine, the operations above enumerated may be executed in quick succession.

' While I have shown what I deem to be the preferable form of my glass-working machine I do not wish to be limited thereto as there might be various changes made in the details of construction and arrangement of parts described without departing from the spirit of the invention comprehended within the scope of the appended claims.

Having described my invention what 1 claim as new and desire to secure by Letters Patent is:
